NOTES:
œ
This table shows the maintenance for up to 8000 hours. After this, repeat from the start or the table.
œ
For places with symbols such as
E
(
k
) and
F
(
k
), carry out checking and cleaning, and replace if necessary.
œ
This periodic maintenance check table changes considerably according to the using conditions and environment.
œ
Refer to the (POWER FAILURE/DEW/USED TIME) menu for the length of time the unit has been used.
œ
As the life of parts may be shortened if foreign particles and dusts remain accumulated on the tape guides and rotating and contacting portions,
clean if dirty.
œ
Dusts and other foreign particles on the tape guides may also shorten the tape life and lower picture quality, therefore clean thoroughly.
